Safari IOS 13 beta 4 unwanted events fired on tap

Hi,


In safari IOS 12, when I click a item on a webpage, Safari fires up this list of events:

  • touchstart
  • touchend
  • click


In safari IOS 13 beta 4 (but it does the same thing since the beta 1), when I click on an item, Safari fires up this list of events:

  • touchstart
  • touchend

delay like 200 or 300ms

  • mousedown (NEW, this creates a second click…)
  • click


This seems like a broken behaviour and might have been introduced by the support of the mouse.
